WILLIAM H. ()GILVIE AND I VILLIAM L.'BENNEM, OF BROOKLYN, N. Y.

APPARATUS FDR CONSUlVllNG SEWER-GAS.

SPECIFICATION forming part of Letters Patent No. 259,420, dated June 13, 1882.

Application filed March 18, 1882. (N0 model.)

To all whom it may concern:

Be it known that we, WILLIAM HENRY ()GILVIE and WILLIAM L. BENNEM, citizens of the United States, both residing at Brooklyn, in the county of Kings and State of New York, have invented new and useful Improvements in Apparatus for Consuming Sewer- Gas; and we do hereby declare that the following is a full, clear, and exact description and specification of the same, reference being had to the accompanying drawings, which form a part thereof.

Our invention relates to improvements in apparatus such as described in the specification annexed to Letters Patent granted to \Villiam Henry Ogilvie, dated May 24, 1881, and numbered 241,819; and our present invention consists in combining with the pipe P and dome G therein described an impregnating or carbonizing chamber adapted to receive and hold'a certain amount or quantity of hydrocarbon or other suitable liquid adapted to render the sewer-gases passing up the pipe l more readily consumable, the said hydrocarbon or fluid being suspended in said chamber or receptacle, by preference, by means of sponge or equivalent absorbent material.

That our invention may be fully understood, we will proceed to describe the same in detail by the aid of the accompanying drawings,

' which form part of this specification.

In the drawings, Figure 1 represents our inyention, shown partly in section and partly in elevation. Fig. 2 is a sectional View of parts on a larger scale.

In each of the views similar letters of reference indicate like parts wherever they occur.

A represents a gas-main and the supplypipe, by means of which the burner B is fed.

E is the vacuumhead, which is mounted on the head of a short pipe leading from the impregnating-chamber W, the lower end of which is by means of the pipe I? in communication with the dome O of the sewer or the drain pipe D, leading from the main sewer.

The various parts, with the exception of the impregnating-chamber IV, are similar in construction and operation to those described in the specification of the aforesaid Letters Patent No. 241,819, and'will therefore require but slight description in order to fully explain our present invention.

The impregnating-chamber W is formed at w and w"with short supplies for the connection of the pipes 20 and 1?. These supplies are shown tapped with female screws. It will, however, be readily seen that male screws may be employed and the joint made by means of a union-joint or otherwise, if desired.

W is a perforated diaphragm, formed either of wire-gauze or other suitable material, adapted, first, to spread the'gases being drawn up from the sewer and facilitate their impregnation with theyapor of the hydrocarbon or other fluid which is held in suspension by means of the sponge or other material, V with which the chamber is tilled. The diaphragm W also serves as a support for the said material.

The operation of our device is as follows: The flame from the gasjet B being ignited, the gas or air, or both, in the chamber E will be rarefied, thereby creating a Vacuum and drawing up the foul gases from the dome O by means of the pipe P through the chamber W. The gases. while thus passing through the chamber W, becoming impregnated with the vapors of the hydrocarbon fluid, will readily mix with the flame from the jet B and burn with great avidity, thereby not only improving the light of thejet B, but also greatly increasing the suction through the pipe P, and consequently drawing off and consuming a much larger quantity of the foul gases from the sewer l).

The hydrocarbon or other fluid or liquid is supplied to the impregnating or carbonizing chamber XV by means of an opening, 10 which we prefer to close by a screw-cap, 20 although other means may be employed.

Although we have described and shown the invention applied to a gas'jet, (as so com-. monly known,) we can with equal facility apply our device to a burner the flame from which is obtained from gases produced by the decom position of oils or other materials held in position by a wick or other equivalent means.
